The trio of TV stars appeared to be locked up in a makeshift jail cell in the middle of Tottenham Court Road train station complete with burley correction officers as busy commuters made their way to work.

The couple were promoting the UK premiere of Universal TV show Proven Innocent which airs tonight at 9pm.

Ruth, who celebrated her 59th birthday yesterday on St Patrick’s Day, was pictured kissing her husband of nine years through the bars of the jail cell before being thrown in the cell herself.
